Inferno DS is a port of the Inferno Operating system to the Nintendo DS.
Inferno DS aims to use the distributed nature of Inferno with the variety of input methods, for the hardware capabilities of the DS like wifi, touchscreen, graphics & audio (see TechnicalBackground) to create new and interesting ways of interacting with computational resources.
